Problem to be solved: to provide a sensor for recognizing the angle of the knee joint by the electronic sound so that the therapist who performs the ambulatory and ambulatory walking in the walking practice of the long leg orthosis can confirm in real time.The sensor is conveniently attached to a long leg orthosis by a magnet.By detecting the joint angle of the knee joint of the long leg orthosis by walking with the rotary switch in the sensor, it is possible to inform it by the electronic sound of the height of 15 degrees of flexion of the knee joint of the leg of the long leg orthosis and the point that it is moved to the flexion 30 degrees at different heights.Therefore, it is possible to confirm the degree of flexion of the knee joint in the real time by the therapist who performs the ambulatory walking and the ambulatory walking, and to take the appropriate assistance and guidance while considering the difference between the angle of the knee joint of the normal walking, and the risk of the degenerative muscle atrophy by the use of the orthosis. Helps prevent.Diagram【課題】長下肢装具の歩行練習時に装着者と介助歩行を行う療法士がリアルタイムで確認することができるよう膝関節の角度を電子音で知らせるセンサを提供する。【解決手段】センサは、磁石により簡便に長下肢装具に取り付けられる。歩行中の長下肢装具の膝継手の関節角度をセンサ内のロータリスイッチにより検知することで、長下肢装具装着肢の膝関節屈曲１５度と屈曲３０度に可動した時点を異なる高さの電子音で知らせることができる。そのため、装着者と介助歩行を行う療法士がリアルタイムで膝関節の屈曲度を確認でき、正常歩行の膝関節の角度との相違を考慮しながら適切な介助や誘導を行うことで正常歩行に発揮される筋活動を促し、装具を使用することで生じる廃用性筋萎縮の危険性を防ぐことに役立つ。【選択図】図２
